[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 5 ,

[0035] First embodiment:

[0036] The present invention provides a technical solution: a highly secure automotive wire harness protective sleeve, including two protective sleeve bodies 1, an anti-slip pattern 2 is sleeved outside the protective sleeve body 1. By setting the anti-slip pattern 2, the anti-slip pattern 2 can prevent slipping when the protective sleeve body 1 is rotated; a plurality of wire groups 4 are arranged inside the protective sleeve body 1, and an isolation component 3 for separating the plurality of wire groups 4 is arranged inside the protective sleeve body 1. A front surface of one of the protective sleeve bodies 1 is connected with an anti-disengagement component 5 for limiting and fixing the wire group 4, and the same steering component 6 for freely rotating the wire group 4 is connected between the two protective sleeves.

[0037] Specifically, as Figures 2 - 4As shown, the isolation component 3 includes a sleeve 31, a first rubber plate 32 is connected inside the sleeve 31, several through holes 33 are formed in the first rubber plate 32, and multiple wire groups 4 respectively penetrate through the corresponding through holes 33. The anti-disengagement component 5 includes a fixing plate 51 and a connecting plate 56. The fixing plate 51 is clamped on the front surface of a protective sleeve body 1. Several round holes 52 are formed in the fixing plate 51, and the wire group 4 penetrates through the round holes 52. A ratchet wheel 53 is rotatably connected to the front surface of the fixing plate 51, and a handle 55 is connected to the front surface of the ratchet wheel 53. By setting the handle 55 and the ratchet wheel 53, rotating the handle 55 can synchronously rotate the ratchet wheel 53. Several rotating holes 54 are formed in the ratchet wheel 53. The connecting plate 56 is connected to one side of the fixing plate 51. A fixed shaft 57 is connected to the front surface of the fixing plate 51. A pawl 58 is rotatably connected to the outside of the fixed shaft 57. The pawl 58 is clamped in the ratchet wheel 53. A torsion spring 59 is sleeved on the outside of the fixed shaft 57. By setting the torsion spring 59, the torsion spring 59 applies an elastic force to the pawl 58, and the elastic force drives the pawl 58 to rotate synchronously, so that the pawl 58 quickly resets. The number of the rotating holes 54 is the same as that of the round holes 52, and the positions of the rotating holes 54 and the round holes 52 correspond to each other. The wire group 4 penetrates through the rotating holes 54. An elastic rubber plate for protecting the wire group 4 is arranged around the inner wall of the rotating hole 54, and the diameter of the rotating hole 54 is slightly larger than that of the round hole 52. By setting the rotating hole 54 and the wire group 4, the diameter of the rotating hole 54 is larger than the diameter of the end face of the wire group 4, so that the wire group 4 can be fitted during rotation, and a large frictional force is generated between the two, thereby realizing the fixation of the wire group 4. One end of the torsion spring 59 is connected to the front surface of the connecting plate 56, and the other end of the torsion spring 59 is connected to the back surface of the pawl 58.

[0038] During operation, by respectively threading multiple wire groups 4 into the corresponding through holes 33, passing through the fixing holes 64, the round holes 52 and the rotating holes 54, and then rotating the handle 55 counterclockwise, the ratchet wheel 53 is driven to rotate on the fixing plate 51. During this process, the ratchet wheel 53 applies a thrust to the multiple wire groups 4 through the rotating holes 54. When the ratchet wheel 53 rotates to a specific tooth block position, the torsion spring 59 applies an elastic force to the pawl 58, causing the pawl 58 to rotate around the fixed shaft 57 and snap into the corresponding position of the ratchet wheel 53. This structure realizes the limitation of the multiple wire groups 4 and prevents the problem that the wire groups 4 slide in the protective sleeve body 1 when the wire groups 4 are pulled.

[0039] Second Embodiment:

[0040] Specifically, as Figure 5As shown in the figure, the steering component 6 includes a corrugated pipe 61. By providing the corrugated pipe 61, the corrugated pipe 61 can freely expand and contract and turn; both ends of the corrugated pipe 61 are connected to the outside of the protective sleeve body 1. Two mounting plates 62 are connected to both ends of the corrugated pipe 61. The same second rubber plate 63 is connected inside the two mounting plates 62. A number of fixing holes 64 are provided inside the second rubber plate 63. By providing the fixing holes 64 and the wire group 4, the fixing holes 64 cooperate with the wire group 4, so that the fixing holes 64 can isolate the wire group 4 when it rotates; a plurality of the wire groups 4 respectively penetrate through the corresponding fixing holes 64.

[0041] When it is necessary to rotate the wire group 4, only need to rotate one of the protective sleeve bodies 1, and this protective sleeve body 1 will drive the corrugated pipe 61 to rotate together, so that the internal wire group 4 rotates synchronously. At the same time, the second rubber plate 63 can limit the wire group 4 to prevent excessive friction of the wire group 4 during rotation.

[0042] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
